Please send more context as of the "green numbers".

For the multiplication,

i 49 x 10 = 490
490 ÷ 10 = 49

ii 2.3 ÷ 10 = 0.23
0.23 x 10 = 2.3

iii 0.034 x 1000 = 34
34 ÷ 1000 = 0.034

iv 876 ÷ 100 = 8.76
8.76 x 100 = 876

Hope this helps :)

Solve the equation. Then check your solution. 5/9d = 9/10

sdas [7]

Answer:

$d=1.62$

The equation is TRUE.

Step-by-step explanation:

To solve the given equation:

$\frac{5}{9}d=\frac{9}{10}$

You need to find the value of the variable "d". You can apply this procedure:

- Multiply both sides of the equation by 9:

$(9)(\frac{5}{9}d)=(\frac{9}{10})(9)\\\\5d=\frac{81}{10}\\\\5d=8.1$

- Divide both sides of the equation by 5:

$\frac{5d}{5}=\frac{8.1}{5}\\\\d=1.62$

Check the solution substituting the value of "d" into the equation and evaluating:

$\frac{5}{9}(1.62)=\frac{9}{10}\\\\0.9=0.9\ (TRUE)$

The local home improvement store wants to increase their inventory. Last year 40 lawn mowers cost them $4,776.

Illusion [34]

To solve this, set up a proportion where X is the amount that 120 lawn mowers would cost. It would look like $\frac{40}{4776}=\frac{120}{x}$ .

Then cross-multiply to get 40x = 120(4776) or 40x = 573120. Now divide each side by 40 to isolate the variable.

X = 14328.

120 lawn mowers would cost $14,328.
